COUNTER-IRRITATION INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 599,714, dated March 1,1898.

Application filed February 15, 1897. Serial No. 623,436. (No model.)

To 0. whom it may concern:

Be it known that LWALTER H. LOCKERBY, a citizen of the United States,residing at Ithaca, in the county of Tompkins and State of New York,have invented certain new and useful Improvements in Counter-IrritantInstruments; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as-will enable othersskilled in the art to which it appertains to make and use .the same.

This invention relates to a novel construction in a device for producingcounter-irritation or blistering of the skin.

The object of the invention is to produce a device of this kind whichwill occupya small space and can be easily carried around, while at thesame time it will always be ready for operation. I

The invention consists'of features of con struction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a central vertical section. Figs. 2 and 3 are crosssectionson the lines 22 and 3 3 of Fig. 1.

Referring now to said drawings, 1 indicates a cylinder provided withcontracted ends having apertures 2 and 3, said apertures 2 and 3.

being centrally located and tapered slightly to receive the stoppers 4and 5, hereinafter The cap 7 is provided with a contracted rear endportion, which connects with the rubber air-bulb 10 for forcing air intothe cap, and between the cap and its contracted end are the cross-pieces11', carrying the stopper 5. The cylinder 1 has a porous filling toabsorb certain chemicals or solutions the vapor of ,which causes anirritation to the skin-for instance, the oil of mustard.

In using this device the end of the flaring mouth 8 is placed close tothe skin, but not touching the same, and then by using the air- The endportions of the cylin forcing device air is forced through the por- 'ousabsorbent, so that it issues at the other end of the cylinder laden withthe vapor of the solution within the cylinder, and thus will' producethe blister or irritant efiect on the skin. When the device is not inuse, the caps 6 and 7 can be screwed inwardly, so that the stoppers canbe fastened securely and prevent the escape of the solution therein.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A device of the kind specified consisting of a chamber open at bothends, longitudinally-movable caps secured to the ends of said chamberand provided interiorly with stoppers situated opposite the open ends ofsaid chamber, whereby when the caps are moved inwardly, the ends of thechamber are closed and when they are moved outwardly, the ends .of thechamber are open, one of said caps having an open outer end, and anair-forcing device communicating with the other of said are passages.-

2. A device of the kind specified consisting of acylinder havingop'enends, a movable cap 6 having a screw-threaded connection with oneend of said cylinder and provided with an interior stopper 4 adapted toclose the end of the cylinder, a flaring mouth upon said cap 6, a cap 7having a screw-threaded connection with the other end of the cylinderand hav ing an interior stopper 5 adapted to close the end of thecylinder, and an air-forcing device communicating with the outer end ofsaid cap 7, while between the stoppers and the caps are passages.

3. A device of the kind specified consisting of a chamber havingcontracted ends provided with apertures 2 and 3, longitudinallymovablecaps secured to the ends of said chamber and provided interiorly withstoppers that are adapted to close said apertures when the caps aremoved inwardly and to open said apertures when the caps are movedoutwardly, the outer end of one ofsaid caps being open, and anair-forcing device communicating with the outer end of the other of saidcaps, while between the stoppers and the of a cylinder 1 having its endportion exteriorly screw-threaded, the ends of said cylinder beingcontracted and provided with apertures 2 and 3, a cap 6 having its innerend screw-threaded interiorly to fit upon the end of said cylinder, theouter end of said cap 6 being provided with a flaring mouth 8, andcross-pieces 9 Within the said cap carrying the stopper 4 that isadapted to fit the aperture 2 upon this end of the cylinder, a cap 7interiorly screw-threaded to fit upon the other end of the cylinder andprovided at its outer end with an opening communicating with anair-forcing device, and cross-pieces 11 Within said cap 7 carrying astopper 5 that is adapted to fit Within the aperture 3 at this end ofthe cylinder.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.

WALTER I-I. LOOKERBY.
